What do you guys know about window air conditioners? I am about to go and buy 3 air conditioners – one 220v and two 120v. My plan of action before consulting google was this: measure the rooms, calculate approximate BTU needed and buy some Panasonic or Fedders brand units and arrange for delivery and professional installation (I’ve installed enough air conditioners myself, and I don’t want to do it anymore now that I can afford it). Well, I searched on the web and in newsgroups a bit and so far my plan is unchanged.
